Applieation filed May 9, 1913. Serial No. 766,603.

To all whom it may concern:

Be it known that l, PERCY 'W. Simona, a citizen of the United States, residing at the city of Los Angeles, in "thecounty of l os Angcles and State of California, have in vented new and useful Improvements in Valves, of which the following is a specification.

My invention relates primarily to a valve for that class of enoine in which liquid l1ydrocarbon is commingled with air so as to form an explosive mixture which is exploded in the cylinders of the engine, and is primarily designed for use on an automobile, and the object thereof is to provide means when desired. to supply an automatically regulated quantity of air into the manifold oi an internal combustion enginebetween the carburetor and the 'cylindeis and to thoroughly mix the air with the mixture passing through the manifold. l accomplish this object by the mechanism described herein andillustrated in the accompanying drawings forming a part hereof in which; I

- Figure 1-is a top plan of my device. Fig. 2 is a section on the line 2- -2 of Fig. 1. 3 is a side elevationof my de ice with a part. of the carburetor and a part of the mnnitl old connected 'lzher'eto Fig. 4 a seciiion on the line bf llig. 3.

lin the drawings 5 is a cylindrical casing having a flange 7 at one end which when positioned for use is bolted to the arhureter 8. Sn the other end of the casing is a. flange 9.

l which when positioned for use is bolted to the manifold 10. In the side of easing 5 is a port or opening 11 into which is received the inner end of a tubular casinglfl which terms a chamber for the reception and operation of the hollow manually operated ular valve 13 and the automatic valve Casing 12 is held positioned by a 'rew Valve 13 is held in its adjusted position by a stud 16 which passes through a slot 17 in casing 12. An operating); flexible wire 18 is secured to stud 16 by screw 19. Wire in through a flexible casing 20 and is connected to the operating lever 21. pivotally imam-Jed on the base "plate 22. Casing: 20 is secured to base plate -22 and to a lung 2 projocting; :l'rom casing 12. Base plate has c ron of depressions 2:: into which is receivcd :1 knob 25 which is mounted on lever and ho ds said lover against accidental movement. This base plate is preferably fastened upon the steering post ot shown) of the automobile. Casing 12 has ports 25 and 26 which are at ditl'erent distances from its outer end and beyond the valve 18 when said valve is in its open position as shown in Fig. 2. 'ldheinner end of valve 14 is tapered and enters valve 13 and is normally held in contact with valve 13 to close the opening therethrough by spring 26 which is inclosed in the outer portion oi casing 12. In a central hole 27 extending into valve 14; is received a lifting rod 28" which is pivotally mounted in lugs 29 secured upon swinging gate 30. Gate 30 is hinged to casing 5 on the carburetor side thereof and regulates the flow of the mixture from the carburetor. ()pposit'e gate 30 is a screen 31 which is held supported and positioned by spider 32.

In the operation of my device when the maximunrquantity of auxiliary air is desired valve 13 is set at its innermost position as shown in Fig. 2. Thereafter the greater thesuction the greater the swing of gate 30 which moves valve 14 to uncover ports 25 and 26 and slot; 17 thereby admitting the maxiinuin aniount of auxiliary air which cominingles with the mixture from the carbureter in the central chamber of easing 5 and then passes through screen 31 which thoroughly mixes it and then on through the manifold tothe cylinders. The less the suction the less the amount of auxiliary air admitted. By this device the admission of auxiliary air is automatically governed by the suction.

If less amount of auxili. -v air is desired valve 18 is moved to close so much of slot 17 and ports 25 and 26 as will permit the remaining portions to admit the amount of air desired. After being set at this point the action of admitting the air is automatic as before explained. When no auxiliary air is desired valve 13 is moved to entirely close slot 17 and ports 25 and 26. By this construction the amount of auxiliary air is manually regulated and its admission into the claim is:

1. An auxiliary air valve for explosion engrines comprising a casingadapted to bh ;io sitioned intermediate the carburcter and cylinders, said ea adapted to form a part of thc'maniiol. a port in the wall of the casing; a valve chamber casing project ing into said port and secured to said casing,

said valve chamber casing having a longitudinal slot and a plurality of ports therein;

a tubular valve in said valve casing for controlling said slot and ports; means to manually control the position of said valve; a second valve having a central hole extending into the body thereof in said valve casing adapted to close the opening through the tubular valve; a spring mounted in the valve casing to hold said second valve spring pressed upon the tubular valve; a swinging gate valve mounted to swing inwardly in the first mentioned casing; and a rod connected to said gate valve and extending through the tubular valve and into the central hole of the said second valve.

.2. In an explosion engine, a manifold having a channel therein, a swinging gate projeicting across the manifold channel; a port {K aeent to the hinge of said gate; a valve casing surrounding and inclosing said port, said valve lasmg having a slot and ports therein for admitting air thereto; a ma ually operated tuhularvaivc in said casing for controlling said slot and-ports; an auto matically operated valve to controkth open ing through the tubular valve; and eens connected to the gate to operate said automatically operated valve.

In witness that I claim the foregoing it have hereunto subscribed my name this 30th day of April, 1913.
